“What does a psychologist do for schizophrenia?”

Hi - someone with schizophrenia is a person! So that person needs a medical physician, namely, a psychiatrist, for medication. Usually, that person will see a psychologist with whom they will talk about their lives, their feelings, their plans, their problems, etc. That is what a psychologist is for.

Psychologists and other trained mental health professionals may engage the person with schizophrenia in a variety of interventions including, but not limited to, cognitive and behavioral methods to help the person recognize and manage positive and/or negative symptoms, positive social activities/life and leisure development, support in vocational endeavors, psychoeducation (promoting healthy lifestyle choices, nutrition practices, psychiatric medication use, etc.). Sometimes, psychological testing is implemented to address the learning, memory, and other neurocognitive impacts of schizophrenia. Psychologists also provide supportive talk therapy to address issues such as loss/grief associated with the diagnosis,  trauma when present, family guidance, and more.
